Regardless of its legal status, this post is really tacky. It leaves me with a gross feeling, sort of like when the awkward kid in the conversation follows every joke someone makes with the same joke a minute later--when he finally gets it.
The point of (nearly) any blog post should be to "continue the current conversation", whatever that means for your genre. It's very obvious to me that this post does not do that, or really anything else.
This should've linked to the source text, which would've included comments.

It actually is simply a violation of copyright. Anything over 15 lines cited iirc.
